PIX 515E.....Proper DMZ setup PLEASE! *************3 simple objectives****************.

Thank you very much!  Everything you explained makes total since.  I will apply it all on Monday.  I will go ahead and accept your response as the solution, and try and contact you if anything fails to work.

Thanks,

lrmoore,

One other requirement I didn't mention because I didn't know it was an issue is web access to host IN the DMZ.  I can't seem to configure the proper rule to achieve this.  Each time I set up what I think is write it stops web access to the LAN????  Help with this would be greateful, eveything else you suggested worked.

It looks like you have the required entries:
Let's take publiw www server .198 as example:
//--Static XLATE to public IP - check
>static (DMZ,outside) 67.103.180.198 192.168.2.42 netmask 255.255.255.255

//--Permit tcp/80 inbound to public IP - check
>access-list Access_in extended permit tcp any host 67.103.180.198 eq www

//--Acl actually applied to interface - check
>access-group Access_in in interface outside

Those should be all you need to get traffic IN to the server. Now let's examine what can go OUT of the DMZ to outside:

//--Is www traffic from host 192.168.2.42 allowed "in" on the DMZ interface?
//-- If you added this as in my example, the answer is yes
>access-list DMZ_access_in extended permit tcp object-group DMZ eq www any

//-- is the proper server in this group? Yes
object-group network DMZ
 network-object host 192.168.2.42 <==

Does this server have the proper default gateway assigned?
Are you trying to access this server by Public IP from OUTside the network? - If all above conditions check out, then you should be able to.
Are you trying to access this server by Public IP from INside the network? - you can't and this is a design feature of the PIX.

Can you post your current running config, and what exact commands that you try to enter when it stops web access to the LAN?

when I am logged into the server I can not browse the web or ping any external host (i.e. 4.2.2.2) as I can from my LAN.  I need to have access to the web from the server.  If you could, please check this link to see if you can reach it:   http://demo.dmsva.com/prisms/login.cfm
As of last week we could get to this from OUTside our LAN.  Prior to that and I am not sure why or who changed it, only one of to NIC's in the host were enabled, and it's IP address was set with the public IP 67.103.180.198, which resolved to the link I asked you to check.  It makes since to me that you would not be able to reach it, because the domain name in the URL in question is set to the public IP, 67.103.180.198
I support a bunch of developers that have never had a LAN Admin, and they all still have free access to the servers for now.  I can get to the URL internally now because the IP in use on the only enabled NIC is the private address 192.168.2.42.  I posted the config, and I did apply all your suggestions.
The IP setting on the host in question(which I guess is wrong) is...
IP - 192.168.2.42
SM - 255.255.255.0
DG - 192.168.2.1

Two things....

1. "global (DMZ) 1 interface" still shows up in the config, though I removed it by entering "no" in front of this command.  Is there anything else I need to do to get rid of it?  When I run "no global (DMZ) 1 interface" it gives an ERROR stating that it doesn't exist.

2. Is there anything wrong with having muliti honed machines in the DMZ, one have the public and the other having a private IP?  I was informed that his can cause a loop, but in past experience I have seen boxes in a DMZ set up this way?  Basically my question really is, what IP address has to be on the one NIC in a host located in the DMZ if it only has one NIC or is two NIC's needed one with the Public and the other with the Private IP addesses?

The web site works fine.
This looks like the old config that should not work.

In order to browse the internet from the server console, we need to allow that out via the access-list:
 add the following:
access-list DMZ_access_in extended permit tcp object-group DMZ any eq www
access-list DMZ_access_in extended permit tcp object-group DMZ any eq https
access-list DMZ_access_in extended permit udp object-group DMZ any eq domain

>Is there anything wrong with having muliti honed machines in the DMZ,
Yes, it defeats the whole purpose of having a DMZ - that is to have an actual firewall between the DMZ machines and the internal network. When dual-homed, If any DMZ machine is compromised, so is your entire internal network.
My advice - don't do it.

Everything WORKS!

Thanks again lrmoore!

Good advice on the multi honed question.  All my requirements are met so there is no need for me to implement any work around.
